*Mathematical statements* used by mathematicians are usually provable. In other words, the mathematical statement: "volume of a sphere = (4/3)πr^{3}" (where r is the radius of the sphere), has a *mathematical proof*.

(a)What is a *mathematical statement*?

(b) What is a *mathematical proof*?

(c) Explain *the truth of A implies B*

(d) What is a *truth table*?

(e) Suppose X makes the following statement to Y: "If it is hot (above 80^{o} F), Maybelline goes braless." What scenario in the illustrated truth table presents X as a liar?

**The strings**:
S_{7}P_{2}A_{21} (Identity - Physical Property).
**The math**:

Pj Problem of Interest is of type *identity* (physical property). Determining *truth* is an identity problem.

(a) A mathematical statement is an expression that is either true or false. For example, 0 = 0 and 1 = 0 are both mathematical statements. The former is true while the latter is false. The expression 3n + 2 is not a mathematical statement.

(b) A mathematical proof is a group of truthful mathematical statements that as a whole convincingly establish the truth of a given mathematical statement. For example, the group of mathematical statements that establish that the area of a circle is πr^{2} is the mathematical proof of the area of a circle.

(c) Given two statements A (the hypothesis) and B (the conclusion) each of which may be either true or false, the *truth of A implies B* means *it is true that if A is true then B is true*.

(d) A truth table is a presentation of the possible truth values of the individual statements of a complex statement in order to determine when the complex statement is true

(e) Suppose A is the statement :"when it is hot"

B is the statement:"Maybelline goes braless"

X is presented as a liar if it is hot and Maybelline does not goe braless. In other words, A is true but B is false. So, A implies B is false. Second row of truth table.

The *point* **.** is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.

The Universe is composed of *matter* and *radiant energy*. *Matter* is any kind of *mass-energy* that moves with velocities less than the velocity of light. *Radiant energy* is any kind of *mass-energy* that moves with the velocity of light.
